Definitions

  • the invention relates to a device for building up pressure in a storage container for cryogenic liquids with a housing which has at least one Inlet opening for liquid and inside a heating device for evaporation of liquid and a steam line arranged in the upper third of the housing for removing the vapor bubbles formed during evaporation.
  • the filling pressure is 3 to 4 bar just enough for proper engine operation.
  • the use of fuel cells as a vehicle drive is currently one Hydrogen supply under a pressure of 10 bar required.
  • a storage of the Hydrogen at a pressure of 10 bar and a corresponding one is disadvantageous because the Storage capacity due to the decreasing density with increasing temperature of liquid hydrogen drops significantly.
  • the one stored at a pressure of 3 to 4 bar Hydrogen is first compressed to 10 bar before being fed to the fuel cell can be.
  • the pressure increase can, for example, by introducing additional gaseous hydrogen in the storage tank or by evaporating a part of liquid hydrogen can be achieved.
  • Such a device for Pressure build-up is known for example from DE 42 12 626 A1.
  • a mammoth pump is attached to the bottom of the storage tank Pump heating liquid hydrogen partially entering the mammoth pump is evaporated. The resulting gas bubbles tear over liquid hydrogen with a riser up into the gas space of the storage tank, where this is finally evaporated by means of an evaporator heater.
  • the object of the present invention is a device of the type mentioned to demonstrate that a simple, fast and secure way to build pressure in a storage container for cryogenic liquids.
  • a housing is provided in the container, which has at least one inlet opening for liquid. Inside the case there is a heating device with the help of which part of the liquid can be evaporated.
  • the resulting steam is fed through a steam line dissipated into the headspace of the storage container.
  • the cross section of the steam pipe is chosen so that the flow resistance of the gas bubbles is so low that they carry little or no liquid with them. In contrast to one Mammoth pump or bubble column is therefore not in the headspace of the storage tank second heating necessary to evaporate the liquid transported upwards.
  • the cross-sectional area of the steam line is advantageously greater than the sum of the Cross-sectional areas of the operation of the device simultaneously through this Cross-sectional area of the steam line passing through steam bubbles.
  • the cross section the steam line is accordingly based on the performance of the heater to interpret.
  • the steam line is preferably arranged at the highest point of the housing. In this way, essentially only steam is present at the entrance to the steam line, so that a transport of liquid through the steam line almost completely is excluded.
  • the housing and / or the steam line are advantageously thermally insulated.
  • the housing and / or the steam line are preferably insulated in that they are double-walled and the gap between the Both walls have an inlet opening for steam and / or liquid.
  • the invention in addition to the device for building up pressure, relates to one Storage container also on a storage container for cryogenic liquids.
  • This has a housing inside, preferably near its bottom, which has at least one inlet opening for liquid and one inside Has heating device for the evaporation of liquid.
  • a Steam line for removing the vapor bubbles created during evaporation. According to the cross section of the steam line is so large that more steam than Liquid is discharged through the steam line.
  • thermodynamic system present in the tank is therefore endeavors to reconcile hydrogen gas by condensing it back bring about thermal conditions of gas and liquid.
  • Such a storage container is therefore advantageously improved in that the Storage containers through a variety of partitions that result from a bad heat-conducting material, is divided into cells, the maximum Expansion in a plane perpendicular to the partition walls less than 50 mm, is preferably less than 10 mm, particularly preferably less than 5 mm. Because of the Use of partitions in the storage container and the invention Dimensioning of the resulting cells is therefore ensured that a or already present in the liquid stored in the storage container targeted temperature stratification remains.
  • the invention has been particularly useful in the storage of liquid hydrogen proven in a motor vehicle.
  • FIG. 1 there is a storage container 1 for a hydrogen-powered vehicle Fuel cell technology is shown, which under driving hydrogen under a pressure of 10 bar is required.
  • the hydrogen is initially at low pressure, for example 1 to 4 bar, in the storage container 1 via the Feed line 2 introduced.
  • the pressure in the container 1 increased by vaporizing liquid.
  • the steam line 5 has a diameter of 20 mm.
  • the housing 3 and the steam line 5 are double-walled, the gap 6 existing between the walls is an inlet and Has outlet openings 7, 8 for liquid or gas.
  • the one through this Inlet openings 7, 8 penetrating into the gap 6 liquid or gaseous Hydrogen is used for insulation between the rising in the steam pipe 5 gaseous hydrogen and the liquid hydrogen surrounding the housing.
  • the storage container 1 is arranged by a plurality of vertically Partitions 10 divided, which are shaped and glued together so that results in a honeycomb structure in cross section.
  • the maximum extension 11 one of these honeycomb cells in a plane perpendicular to the partition walls 10 is 6 mm.
  • the partitions themselves consist of a resin soaked in resin Knitted fabric, which is impermeable to liquids and poorly conductive.
  • the uppermost layers of liquid form an insulating layer prevent further back condensation.
  • a pressure of 10 bar which has a boiling temperature of about 31 K. corresponds to maintain, while the liquid hydrogen to about 25 K. is hypothermic.
  • the additional subdivision of the storage container 1 into individual cells prevents liquid movements in the storage container 1 that lead to a Destruction of the temperature gradient in the liquid hydrogen could result.
  • the gaseous hydrogen is fed to the fuel cells via line 13.
  • the invention thus makes it possible to use hydrogen in liquid form at low Temperature is stored in gaseous form under high pressure of, for example, 10 bar to provide.
